Mary Boyce Temple (July 6, 1856 – May 16, 1929) was an American philanthropist and socialite, active primarily in Knoxville, Tennessee, in the late 19th and early 20th centuries.

[2] Temple was the founder and long-time regent of the Bonny Kate Chapter of the Daughters of the American Revolution,[2] and helped launch Knoxville's preservationist movement with her efforts to save Blount Mansion in the 1920s.

[1][2] Her father was a powerful Knoxville attorney who, at one point after the American Civil War, had the highest personal income in Knox County.

Temple was educated at the East Tennessee Female Institute in Knoxville, where she was classmates with the painter Adelia Armstrong Lutz.

[7] In 1885, Temple was elected first president of the Ossoli Circle, a women's literary club founded that year by activist Lizzie Crozier French.

She was the lone woman on the Jury of Higher Education at the St. Louis World's Fair in 1904, and helped organize Knoxville's National Conservation Exposition in 1913.

"[2] The Mary Boyce Temple House, located at 623 Hill Avenue in Knoxville, is the last single-family residence in the city's downtown area.

[7] After a series of ownership changes and modifications over the decades, the house, threatened with demolition, was purchased in 2006 by Brian Pittman, who has since taken steps to renovate and restore it.
